* Replace the linear search in vm_map_findspace() with an O(log n)Alan Cox2004-08-132-98/+213
| | | | | | | | | | | | | | | | | | | | | | | | algorithm built into the map entry splay tree. This replaces the first_free hint in struct vm_map with two fields in vm_map_entry: adj_free, the amount of free space following a map entry, and max_free, the maximum amount of free space in the entry's subtree. These fields make it possible to find a first-fit free region of a given size in one pass down the tree, so O(log n) amortized using splay trees. This significantly reduces the overhead in vm_map_findspace() for applications that mmap() many hundreds or thousands of regions, and has a negligible slowdown (0.1%) on buildworld. See, for example, the discussion of a micro-benchmark titled "Some mmap observations compared to Linux 2.6/OpenBSD" on -hackers in late October 2003. OpenBSD adopted this approach in March 2002, and NetBSD added it in November 2003, both with Red-Black trees. Submitted by: Mark W. Krentel Notes: svn path=/head/; revision=133636

| | | | | | | | | | | | | | | | * Restructure the event handling path. acpi_tz_thread() now calls acpi_tz_timeout() any time an event occurs. acpi_tz_timeout() checks the flags and calls acpi_tz_power_profile(), acpi_tz_establish(), and acpi_tz_monitor() as appropriate. Notifies only do a wakeup and let acpi_tz_thread() do the actual work. This path is cleaner and allows locking since the call path is now always a D.A.G. * Add the acpi_tz_signal() function to set flags and wake the thread. * Remove the tz_tmp_updating flag since calls are serialized by acpi_tz_thread(). * Remove Giant locking.

* Add the ability to associate ipfw rules with a specific prison ID.Christian S.J. Peron2004-08-122-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the only thing truly unique about a prison is it's ID, I figured this would be the most granular way of handling this. This commit makes the following changes: - Adds tokenizing and parsing for the ``jail'' command line option to the ipfw(8) userspace utility. - Append the ipfw opcode list with O_JAIL. - While Iam here, add a comment informing others that if they want to add additional opcodes, they should append them to the end of the list to avoid ABI breakage. - Add ``fw_prid'' to the ipfw ucred cache structure. - When initializing ucred cache, if the process is jailed, set fw_prid to the prison ID, otherwise set it to -1. - Update man page to reflect these changes. This change was a strong motivator behind the ucred caching mechanism in ipfw. A sample usage of this new functionality could be: ipfw add count ip from any to any jail 2 It should be noted that because ucred based constraints are only implemented for TCP and UDP packets, the same applies for jail associations.

* - Introduce an ofw_bus kobj-interface for retrieving the OFW node and aMarius Strobl2004-08-1250-738/+738
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | subset ("compatible", "device_type", "model" and "name") of the standard properties in drivers for devices on Open Firmware supported busses. The standard properties "reg", "interrupts" und "address" are not covered by this interface because they are only of interest in the respective bridge code. There's a remaining standard property "status" which is unclear how to support properly but which also isn't used in FreeBSD at present. This ofw_bus kobj-interface allows to replace the various (ebus_get_node(), ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type() vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one. This in turn allows to simplify and remove code-duplication in drivers for devices that can hang off of more than one OFW supported bus. - Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the drivers for their children to use the ofw_bus kobj-interface. The IVAR- interfaces of the Central, EBus and FHC are entirely replaced by this. The PCI bus driver used its own kobj-interface and now also uses the ofw_bus one. The IVARs special to the SBus, e.g. for retrieving the burst size, remain. Beware: this causes an ABI-breakage for modules of drivers which used the IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be recompiled. The style-inconsistencies introduced in some of the bus drivers will be fixed by tmm@ in a generic clean-up of the respective drivers later (he requested to add the changes in the "new" style). - Convert the powerpc MacIO bus driver and the drivers for its children to use the ofw_bus kobj-interface. This invloves removing the IVARs related to the "reg" property which were unused and a leftover from the NetBSD origini of the code. There's no ABI-breakage caused by this because none of these driver are currently built as modules. There are other powerpc bus drivers which can be converted to the ofw_bus kobj-interface, e.g. the PCI bus driver, which should be done together with converting powerpc to use the OFW PCI code from sparc64. - Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take advantage of the ofw_bus kobj-interface and simplify them a bit.
